Abstract: A process for the incremental enrichment of deuterium and/or tritium in a material which is suitable for the isotope exchange of deuterium and tritium with hydrogen, and an arrangement for the implementation of the process. The process and arrangement for the enrichment of deuterium and/or tritium in water which, in addition to a high transport speed for the molecules which participate in the isotope exchange, evidences a high enrichment factor for each enrichment stage and a high yield, so that at a relatively small number of stages and low energy consumption there is attainable an overall high degree of enrichment. For each enrichment stage, water containing deuterium and/or tritium is introduced into a carrier gas flow, reduced and set to a hydrogen (H2) partial pressure of maximally 100 mbar. Subsequent thereto, the carrier gas flow is conveyed along the primary side of an exchange wall which is suitable for the permeation of hydrogen, along the secondary side of which there flow a further carrier gas flow which contains a material adapted for the isotope exchange of deuterium and tritium with hydrogen in the gas phase thereof. The hydrogen isotopes deuterium and/or tritium which permeate through the exchange wall, after the isotope exchange, are bonded with the material in reaction product.

Abstract: Bei der NMR-Tomographie werden die in einem ausgewählten Bereich eines Körpers enthaltenen, ausgewählten Kernspins dadurch selektiv angeregt, daß nach Anlegen eines Selektions-Gradientenfeldes die Kernspins durch ein HF-Signal angeregt werden, das zunächst eine Drehung der in einer ausgewählten Ebene angeordneten Kernspins um einen weniger als 90° betragenden Winkel α, dann eine Drehung aller ausgewählten Kernspins im 90° und endlich wiederum eine Drehung der sich in der ausgewählten Ebene befindenden Kernspins um einen Winkel von 90° -α bewirkt. Als Ergebnis befinden sich nach dieser Anregung die in dem ausgewählten Bereich enthaltenen Kernspins in der ursprünglichen, durch ein homogenes Magnetfeld bestimmten Richtung, während die außerhalb dieses Bereiches vorhandenen Kernspins in einer dazu senkrechten Ebene liegen. Danach kann ein Lese-Gradientenfeid eingeschaltet werden, ohne daß dadurch die Orientierung der in dem ausgewählten Bereich enthaltenen Kernspins gestört wird. Bei eingeschaltetem Lese-Gradientenfeld werden nun die Kernspins durch einen 90°-Impuls oder übliche Impulssequenzen angeregt, so daß sie ein Induktionssignal erzeugen. Die Meßvorgänge werden jeweils paarweise unter Anwendung unterschiedlicher Anregungssignale bei anliegendem Selektions-Gradientenfeld ausgeführt, derart, daß die im ausgewählten Bereich enthaltenen Kernspins abwechselnd entgegengesetzte Richtung haben, so daß die von ihnen erzeugten Induktionssignale um 180° phasenverschoben sind, wogegen die außerhalb des ausgewählten Bereiches liegenden Kernspins stets in gleicher Weise beaufschlagt werden, so daß sie,wenn überhaupt, identische Signale liefern. Durch Subtraktion der bei aufeinanderfolgenden Messungen erhaltenen Induktionssignale werden die von den außerhalb des ausgewählten Bereiches vorhandenen Kernspins gelieferten Signale eliminiert, wogegen sich die gegenphasigen Signale, welche die in dem ausgewählten Bereich enthaltenen Kernspins liefern, addiert werden.

Title: Redundant control actuation system-concentric direct drive valve

Abstract: A redundant control actuation system (70) for an aircraft including an electro-mechanically controlled, hydraulically powered actuator (72) for driving a main control valve (30) of a servo-actuator control system (10). The actuator includes a tandem piston (74) connected to the main control valve and a force motor driven tandem pilot valve (190) axially movable in the piston for simultaneously controlling the differential application of fluid pressure from respective hydraulic systems on opposed pressure surfaces (114 and 118, 120; 122 and 124, 126) of respective piston sections (104, 106) to cause movement of the piston (74) in response to relative axial movement of the pilot valve (190) as long as at least one hydraulic system remains operative. The piston pressure surfaces are sized and arranged to minimize force unbalance on the piston due to pressure variations in the hydraulic systems. Also, a pilot valve centering spring device (284) may be provided to minimize undesirable transient motions during system turn on and shut down. Upon failure or shut down of both hydraulic systems, a shut off valve sleeve (162) concentric with the pilot valve (190) moves axially in the piston (74) to render the pilot valve inoperative and release fluid pressure from opposed, corresponding pressure surfaces of the piston sections to respective returns therefor through centering rate control orifices (150, 266 and 148, 268) as the piston is moved to a neutral position by a centering spring device (282) acting on the main controle valve (30).

Abstract: Optionally alkyl-substituted 3,4-dihydro- alpha -pyrones are prepared by thermolysis of the corresponding 5-hydroxymethyl-2(3H)furanones. It has been found that this known thermolysis can be carried out in the presence of a large number of catalysts even at relatively low temperature. The catalysts which can be employed include oxides and mixed oxides of the elements of main groups III and IV and sub-groups IV to VII of the periodic table of the elements. Zinc oxide and mixed oxides of magnesium can also be employed. In addition, the catalysts which can be employed include sulphuric and phosphoric acids and their organic derivatives. Lewis acids can also be employed as catalysts. The catalytically particularly active mixed oxides of aluminium and silicon principally include layer silicates and aluminosilicates. In a specific embodiment, the reaction is carried out in high-boiling solvents. In this procedure, the resultant dihydropyrone is expediently removed from the reaction medium together with the water of reaction immediately after its formation.
